Spongilla Lacustris is a freshwater sponge common in Europe. Sponge spicules are structural components functioning as a "skeleton" and defense system against predators and consisting of calcium carbonate, silica, and Chitin.
Spongilla Lacustris spicule extract is a multifunctional skincare ingredient that comprises all benefits of its natural components. Fine particles are used as an abrasive for mechanical exfoliation or dermabrasion, which polishes and eliminates old, pigmented, and dead cells from the skin surface, exposing a fresher, clearer, and radiant appearance.
Chitin is a long-chain polysaccharide consisting of glucose units, the second most abundant natural polymer after cellulose with similar characteristics. Spongilla Lacustris spicule contains α-chitin. It provides flexibility and strength to spicules and insect exoskeletons. It is not soluble in water, but its derivative chitosan is water-soluble and widely used in skin care applications.
Chitin is a perfect texturizing and bulking agent that provides a rich and soft feel. It has similar properties to keratin and is used in hair care formulations for brittle or damaged hair. In addition, thanks to natural antibacterial action against Streptococcus and other bacteria, Chitin is an ideal ingredient for preparations against acne and other skin infections.
In addition, it protects skin from UV exposure, moisturizes and improves water-retention ability (especially in combination with glucans), and binds another active ingredient assisting in the delivery and enhancing the formula's stability. Spongilla Lacustris spicule extract is a natural, sage, and renewable ingredient to preserve the skin's beauty and radiant glow.
